Ventrodorsal and right lateral views of the abdomen are available. There
is increased soft tissue opacity noted dorsal to the urinary bladder and
ventral to the colon on the lateral view consistent with uteromegaly.
There is a soft tissue opacity tubular structure superimposed over the
apex of the urinary bladder on the lateral view that could potentially
represent a uterine horn, or small intestinal bowel loop. The small
intestines are diffusely fluid filled, and all tubular structures within
the abdomen are relatively similar in size. There is a soft tissue opacity
that measures roughly 6 x 6.5 cm in size caudal to the right kidney. There
is an ill-defined and wispy to striated hazy appearance associated with
the tubular soft tissue structures in the abdomen. No other abnormalities
are noted.

DIAGNOSTIC INTERPRETATIONS:

Uteromegaly and soft tissue mass caudal to the right kidney that is
thought to represent an ovarian structure may be indicative of cystic
ovarian disease, or potentially an ovarian tumor in addition to the
patient's probable pyometra. The wispy abdominal contrast raises concern
for mild effusion or inflammatory reaction secondary to the possible
pyometra. Recommend abdominal ultrasonography for further evaluation and
possibly a surgical explore.
